Python reverse() for palindromes

python reverse palindrome

Matthew Sainsbury · Mar 5, 2011 · Viewed 15.5k times · Source

I'm just getting started in python, and I'm trying to test a user-entered string as a palindrome. My code is:

x=input('Please insert a word')
y=reversed(x)
if x==y:
    print('Is a palindrome')
else:
    print('Is not a palindrome')

This always returns false because y becomes something like <reversed object at 0x00E16EF0> instead of the reversed string. What am I being ignorant about? How would you go about coding this problem?

Answer

Try y = x[::-1]. This uses splicing to get the reverse of the string.

reversed(x) returns an iterator for looping over the characters in the string in reverse order, not a string you can directly compare to x.
